In order toreinforce the spinning spools or 1 sh ws a, or t d reinforced sp 1 shells during the spinning, washing, after treatwith a pipe sh d extension 2, which i used for 1 ment and'drying, theyare mounted upon removplacing the reinforced spool on the spool spindle able reinforcements which strengthen the spools 14 of the artificial silk spinning machine, whereby from the inside.

These interior reinforcealso as a flow pipe for the Washing and further treatment liduids, if the spinning material 4 wound onthe auxiliary spool 3 is subjected to the washing and further treatment processes.

Fig. 2 shows the reinforcing spool together with the pipe 'shapedextension2, Fig. 3 aperforated auxiliary spool 3, which canbe pushed over the reinforcing spool 1 according to Fig. 2.

Figures 4 and 5 show the reinforcing- 815001; on

which .the shell 6 can be pushed and which can have a handle '7. The real spool 8 according to the invention is placed over this shell and the coil 9 is then placed thereon, .The between shell 6, which can, for exampla consist of metal or of any other materials, can have a slit on one of the sides as is shown in Fig. 5. The reinforcing spool .5 can also have a lug, which is shown'inthe drawing so that the shell cannotbemoved in 'a radial direction on the reinforcing spool but can be with-' drawn in the axial direction. If this shell is made with spring properties the slit can decrease after the removal of the reinforcinglspool 5 and the 7 Shell on its part easily removed from the body of .the cOiL.
